Memory leakage / memory problems

[Peter T. Evensen]

Look at your app in the task manager and look at the Process Tab and Memory 
usage.

If that keeps going up and up as you use the program, you have a leak some 
place.  It may fluctuate, as you go different stacks and cards.  If you 
have a main menu screen, however, it should return to a constant value 
every time you return there.   If you go into your program and back to the 
main screen and the number goes up each time you do that, you definitely 
have a memory leak someplace.

Another potential source of memory leaks is externals.  Do you use any 
externals?
